Lets say I have a plane, with the four co-ordinates:
(0,0,0)
(0,0,1)
(1,2,0)
(1,2,1)
So it's a basic plane with a gradient of 2 in x axis and 0 in the others? -I can figure that out just by plotting/looking at it.
How could I work the gradient out of any given (assuming four co-ords form a flat surface) plane?
I'm very confused when it comes to vectors/matrix's/co-ords/transformations etc... But I need to know the gradient of planes for a java3d project I'm making.
